Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a water purifier that does not require pipe removal. Background Technology

[0002] As people's living standards improve, water purifiers are becoming increasingly popular. To facilitate cleaning and replacing filter components, water purifiers that do not require disassembly have emerged on the market. However, existing water purifiers that do not require disassembly have the following problems:

[0003] Portable water purifiers are characterized by a guide tube of equal length to the filter assembly located in the middle of the filter assembly. This structure has several drawbacks: 1. When installing or removing the filter assembly, the installation space on one side of the water purifier's outer casing must be larger than the length of the filter assembly; otherwise, it cannot be installed or removed. 2. The guide tube hinders cleaning the filter assembly, affecting its ease of cleaning. 3. An O-ring seal is located on the guide tube furthest from the filter head; this O-ring seal makes tight contact with the internal interface of the outer casing, requiring significant manual labor to remove the filter assembly, which is time-consuming and labor-intensive. 4. The guide tube increases material and assembly labor costs.

[0004] The water purifier with filter cartridge cleaning without disassembling the connecting pipe has the following structural features: the outer diameter of the two annular sealing rings assembled in the annular groove of the filter component is similar to the outer diameter of the outer shell (generally the reference size is an outer diameter of 90-400mm). The filter component is installed in the water purifier shell, and the two annular sealing rings press against the corresponding circular protrusions on the inner wall of the water purifier shell. The shortcomings of this structure are as follows: 1. When installing the filter assembly at the factory, installers need to use a lot of manpower to press the filter assembly against the corresponding circular protrusion on the inner wall of the outer shell, or they need to configure pneumatic tooling to assemble the filter assembly, increasing equipment investment and assembly steps; 2. The outer diameter of the two annular sealing rings assembled in the annular groove of the filter assembly is large (generally, the reference size is an outer diameter of 90-400mm). When replacing the filter assembly after the sale, after-sales personnel need to use a lot of manpower to repeatedly shake and pull the filter assembly forward, backward, left, and right to remove it. In places where consumers use water purifiers (e.g., homes, enterprises, etc.), it is inconvenient to configure pneumatic tooling. When after-sales personnel install and remove the filter assembly, they can only rely on manual pressing and pulling of the filter element assembly, which is time-consuming, labor-intensive, and inefficient.

[0005] To address the aforementioned issues, this solution is proposed. Utility Model Content

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown (where, Figure 3 (A), (B), and (C) are different views of the filter head 31). This utility model provides a water purifier that does not require disassembly of the pipe, including a housing 1, a housing cover 2, a filter assembly 3, and fasteners 5. The filter assembly 3 includes the filter head 31. The housing 1, the housing cover 2, and the filter assembly 3 are detachably connected by fasteners 5. An elbow 13 is provided on the side wall of the housing 1 near the filter head 31. The filter head 31 is provided with a guide pipe 36, which is connected to the elbow 13.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as an optional embodiment, the guide pipe 36 is disposed on the side of the filter head 31.

[0037] like Figure 1 and Figure 10 As shown, as an optional second embodiment, the guide pipe 36 is located in the middle of the filter head 31.

[0038] like Figure 2As shown, the guide tube 36 can be in the shape of a straight tube;

[0039] like Figure 10 As shown, the guide tube 36 can also be a bent tube.

[0040] Furthermore, it should be noted that the filter head 31 can be integrally formed with the guide tube 36, such as by using the same mold; alternatively, the filter head 31 and the guide tube 36 can be two separately manufactured parts, which are then assembled together, without limitation. Similarly, for a straight guide tube 36, it can be integrally formed using a mold; while for a bent guide tube 36, it can be integrally formed using a mold of the corresponding shape, or multiple molds can be used to manufacture different sections of the guide tube 36, which are then fixedly connected to form the final bent guide tube 36, without limitation. The fixing and connection methods can include welding, adhesive bonding, etc.

[0041] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the guide pipe 36 and the elbow 13 are detachably and sealingly connected. This detachable sealing connection can be achieved by having a guide pipe groove 37 on the guide pipe 36, and a second sealing ring 38 fitted into the guide pipe groove 37.

[0042] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a through hole 12 is provided on the side wall of the outer casing 1 near the filter head 31. An elbow 13 is fixed to the through hole 12. The elbow 13 has an inner circular sealing surface 16. The opening of the end of the elbow 13 with the inner circular sealing surface 16 faces the side where the filter head 31 is assembled. The through hole 12 and the elbow 13 can be connected by welding.

[0043] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, elbow 13 is equipped with a horn guide head 17, which is used to guide the flow guide pipe 36 into the elbow when the filter assembly 3 is assembled.

[0044] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the filter assembly 3 is installed inside the outer casing 1, the guide pipe 36 is inserted into the elbow 13, and the second sealing ring 38 is tightly abutted against the inner circular sealing surface 16 of the elbow, which serves to achieve a seal between the guide pipe 36 and the elbow 13. The function of the guide pipe 36 and the elbow 13 is that the purified water after being purified by the filter element 34 flows back to this end of the outer casing 1 through the guide pipe 36 and the elbow 13, and then flows out of the water purifier from the water outlet 14 on the side wall of the outer casing 1.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the filter head 31 is provided with a limiting ring 32, which serves to limit the filter assembly 3 and prevent the filter assembly 3 from moving towards the outer shell 1 and the outer shell cover 2. The limiting ring 32 is equipped with a first sealing ring 33, which seals and isolates the raw water chamber and the purified water chamber to prevent water from flowing between the raw water chamber and the purified water chamber, and at the same time prevents water in the raw water chamber and the purified water chamber from leaking to the outside of the water purifier.

[0046] like Figure 2 , Figure 5 and Figure 6 As shown, the filter assembly 3 also includes a perforated handle 41. The filter head 31 has a handle mounting hole 39 and a handle step 40. The perforated handle 41 is inserted into the handle mounting hole 39, and the handle step 40 serves to limit the assembly of the perforated handle 41. The perforated handle 41 and the handle mounting hole 39 are fixedly connected, which can be achieved by using adhesives such as glue.

[0047] like Figure 1 and Figure 6 As shown, the outer casing 1 is equipped with a bracket 6 and a steel strip 61, which are used to fix the water purifier.

[0048] like Figure 7 As shown, the water flow principle of the whole machine purification and water production of the pipe-free water purifier is as follows: the raw water inlet 11 is open, the drain outlet 15 is closed, and the purified water outlet 14 is open. The raw water enters from the raw water inlet 11, is filtered by the filter element 34, and then comes out from the purified water outlet 35 of the filter element. The purified water is discharged from the purified water outlet 14.

[0049] like Figure 8 As shown, the water flow principle of the whole machine forward flushing of the water purifier without pipe disassembly is as follows: the raw water inlet 11 is open, the clean water inlet 14 is closed, and the drain outlet 15 is open. The raw water enters from the raw water inlet 11, flushes the dirt on the surface of the filter element 34, and the sewage is discharged from the drain outlet 15.

[0050] like Figure 9As shown, the backwashing principle of the water flow of the water purifier without pipe disassembly is as follows: the raw water inlet 11 is closed, the clean water inlet 14 is open, the drain outlet 15 is open, the raw water enters from the clean water inlet 14, continues to enter the filter element clean water inlet 35, passes through the filter element 34, washes away the dirt on the surface of the filter element 34, and the sewage is discharged from the drain outlet 15.

[0051] The beneficial effects of this utility model are:

[0052] This utility model employs a water guide pipe that exits from the side wall of the outer casing near the filter element head, offering the following advantages: First, the outer casing has no interfaces or pipes, eliminating the need to disassemble the water pipes when removing the water purifier; second, minimal space is required when installing and removing the filter assembly; third, the guide pipe does not interfere with cleaning the filter assembly; fourth, it reduces the material cost of the guide pipe, and eliminates the need for tools and pneumatic equipment when assembling the filter assembly, thus lowering manufacturing costs; fifth, it requires minimal skill in installing, disassembling, cleaning, and maintaining the filter assembly, making operation convenient, time-saving, and labor-saving, thereby reducing after-sales service costs.

[0053] The above description is merely an exemplary embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
